Reject a Dataset-JSON 1.0 File

Review ask

As a clinical trial statistician or programmer, answer two short questions in Your review: the task and the inputs. Agreeing with both approves this benchmark; disagreeing with either needs a comment. Propose a fix with the Edit button on any source file, or add it to your comments.

We suggest spending no more than 5 minutes on a review. The other tabs beside Your review are background for assessment, not under review.

Summary

EditUnder reviewWhat this benchmark means

README.md

Public entries: Python and R. Passing coverage requires an installed inventory.

Goal: build a subject listing carrying SITEID from demographics received as a Dataset-JSON file.

Input: the received demographics input/dm.json, a Clinical Data Interchange Standards Consortium (CDISC) Dataset-JSON file that names version 1.0.0, holding STUDYID, USUBJID and SITEID.

Variables:

SITEID would be the site the subject enrolled at, taken directly from the received demographics.

Only Dataset-JSON 1.1 files are read. A 1.0 file nests its records and their types in another structure, so reading it as 1.1 could give a value a type the sender never gave it. The file is rejected while it is read, before any record is used, and no artifact is accepted.

How to fix

Ask the sender for the dataset as Dataset-JSON 1.1, and read that file. Its first members name the version it follows:

{"datasetJSONCreationDateTime": "2026-09-30T10:15:00",
 "datasetJSONVersion": "1.1.0", ...}

Do not edit the version of a 1.0 file by hand; the version is a property of how the file was written, not a label. A file converted to 1.1, or to CSV, by a tool outside the study is read under the name of what it then holds.

ADSL	STUDYID	Study Identifier	character	Copy value from DM.STUDYID.	Predecessor

Version	Date	Author	Description
1.7	2026-10-20	yamaa docs build	Read a specification in the 1.0 surface as its 0.5 counterpart; state that missing values stay missing where a mapping declares no missing handler, and leave out a declared missing answer that restates a handler's default
1.6	2026-10-17	yamaa docs build	Describe collected date parts written as ISO 8601 date text and times of day counted in seconds since midnight
1.5	2026-10-17	yamaa docs build	Name collected precision in words instead of letter codes; state imputation fallbacks, minimum source precision, bounds ignored outside the collected period, and invalid text with no handler as an error; describe date and datetime shifts, imputation flag codes, and partial text giving no date part
1.4	2026-10-15	yamaa docs build	State datetime precision codes through the hour and minute, and complete only the time parts a collected datetime lacks
1.3	2026-09-29	yamaa docs build	Show study codelist names, external dictionaries, and ISO 8601 formats in variable rows; list the document's codelist values and metadata
1.2	2026-09-29	yamaa docs build	Classify ADaM copies from a declared input as Predecessor and recodes as Derived, and SDTM recodes of locally derived columns as Derived
1.1	2026-09-29	yamaa docs build	Resolve lookups into the donor record they select, and give every derivation shape a plain-language rule instead of its raw YAML
1.0		yamaa docs build	Initial generation from spec.yaml
